Problems solved by technology

[0003] Generally, after dialysis of blood, in order to fully understand the changes in blood components after dialysis, whether there are impurities entering or whether certain cells or components are lost, the blood needs to be separated and tested, so it will be used Blood component separation device, but most of the existing devices separate blood dialysis and component separation, which is not conducive to the rapid detection of blood and low work efficiency

Embodiment 1

[0017] see Figure 1-3 , a multi-stage hemodialysis and blood component separation device, comprising a frame 10, a blood inlet 11, a dialyzer 13, a blood outlet pipeline 20, and a filter chamber 22; The upper side is fixedly installed with a dialyzer 13 in an S-shaped structure through connecting rods on the left and right sides. The top left side of the dialyzer 13 communicates upward with a blood inlet 11 whose end is placed on the outer top of the frame 10. Through the blood inlet 11, the The blood to be treated is input into the dialyzer 13 for dialysis. The interior of the dialyzer 13 is fixedly installed with multiple groups of dialysis membranes 14 for dialysis and filtration of the blood. The dialysis membranes 14 are semi-permeable membranes made of cellulose Dialyzer 13 is made of membrane or synthetic membrane, and by setting dialyzer 13 in a multi-stage S-shaped structure, the blood input into it can pass through dialysis membrane 14 multiple times under the actio...

Embodiment 2

[0019] On the basis of Embodiment 1, the outside of the blood bag 24 is wrapped with a layer of heat preservation layer, which is used to heat the blood input into the blood bag 24 to prevent the temperature from being too high or too low to affect the collection of blood components. activity, thereby affecting the results of subsequent tests.

[0020] The working principle of the present invention is: when in use, at first the blood to be treated is input into the dialyzer 13 through the blood inlet 11, and under the action of gravity, it is fully dialyzed through multiple groups of dialysis membranes 14 respectively, and then passed through the bottom The blood outlets 15 on the left and right sides input the dialyzed blood into the cell filter 16 for centrifugation, and then separate each other through the centrifugal net 21, and then the centrifuged blood falls into the filter chamber 22 under the action of gravity, Then it is filtered through multiple sets of filter membr...

Abstract

The invention relates to the technical field of blood treatment and detection equipment, and discloses a multistage hemodialysis and blood component separation device. The multistage hemodialysis andblood component separation device comprises a frame, a blood inlet, a dialyzer, a blood outlet pipeline and filter cavities; the dialyzer of an S-shaped structure is fixedly installed on the upper side of the interior of the frame through connecting rods on the left side and the right side; a plurality of sets of dialysis membranes used for dialyzing and filtering blood are fixedly installed in the dialyzer at equal intervals; the bottom of the blood outlet pipeline rotationally communicates with a set of cell filters of a spherical structure through a rotary installation valve; the bottom ofeach cell filter is rotatably connected with a rotating seat; the middle part of the rotating seat downwards communicates with the corresponding filtering cavity with the bottom fixed on the ground; acircle of centrifugal net is fixedly arranged in each cell filter; and a plurality of groups of filtering membranes with membrane diameters sequentially reduced are fixedly arranged in the filteringcavity at equal intervals from top to bottom. The multistage hemodialysis and blood component separation device has the advantages of multi-stage dialysis, high accuracy, centrifugation and multi-stage filtration, and high separation precision.

Description

technical field [0001] The invention relates to the technical field of blood processing and detection equipment, in particular to a multistage hemodialysis and blood component separation device. Background technique [0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. Generally speaking, before reading blood for dialysis, it is necessary to pre-test and process, first take a blood sample for dialysis, then test the specific effect of the dialysis, and then judge whether to apply it to the patient. [0003] Generally, after dialysis of blood, in order to fully understand the changes in blood components after dialysis, whether there are impurities entering or whether certain cells or components are lost, the blood needs to be separated and tested, so it will be used A blood component separation device, but most of the existing devices separate the dialysis and component separation of blood, which is not conducive t...
